2026-10-20 06:07:18 UTC (1 hour ago) · approx. 7:07 PM UTC-11 local
On October 20, 2026 at 06:07 UTC, a magnitude 3.2 shallow crustal earthquake struck 36 km ENE of Noatak, Alaska, at a depth of 5.0 km and coordinates 67.7300°, -162.2030°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
